Charges & Cancellations

Changing Reservations:

There is no change fee if a visitor extends or shortens a reservation, as long as the change includes dates from the original reservation. Additionally, there is no change fee if the visitor wants to switch sites that are the same price with the same reservation dates in the same facility.

If a visitor wants to switch dates that are entirely outside of the original reservation dates, there is a $10 change fee.

If a reservation is made that includes dates beyond the maximum booking window, that reservation cannot be changed until 18 days have passed from the original booking date.

Once a reservation date has begun, visitors cannot change a reservation using the online system or through the Call Center. Onsite staff will assist with changes or cancellations. Cancellations:

Visitors may cancel their reservation prior to arrival both on-line and through the call center. A $10 service fee will be withheld from any refund for a cancellation.

A visitor who cancels a reservation the day before or on the day of arrival will pay a $10.00 service fee AND forfeit the first night's approved rate including tax and applicable add-on. Cancellations for a one-night reservation will forfeit the entire amount paid and will not be subject to an additional service fee.

Visitors who cancel a group overnight facility reservation less than 14 days prior to arrival date will pay a $10 service fee AND forfeit the first night’s rate. 


A no-show visitor is one who does not arrive at a campground and does not cancel the reservation by check-out time on the day after the scheduled arrival date. Staff will hold a campsite until check-out time on the day following the arrival date.

No-shows are assessed $20.00 service fee and forfeit the first night's rate, taxes and applicable add-on for a campsite. 

Early Departures:

Visitors are requested to notify staff at the facility if they depart early to allow others to use the site.

If the visitor chooses to depart early, they may forfeit the approved rate and applicable tax and applicable add-on for the day of departure. If a visitor departs prior to the scheduled check-out date, they may be eligible for a partial refund. Visitors may notify the Recreation.gov call center to request a refund of remaining unused nights. If a visitor requests a refund for an early departure after the facility check-out time (10 am) has passed, the visitor will not be refunded for that night and is eligible for a refund on any additional nights that will not be used.
